Control Circuit Inspection

Check voltage
1. IG "OFF".
2. Disconnect ETS motor & TPS connector.
3. IG "ON" and ENG "OFF"
4. Measure the voltage between terminal 2,3 of ETS motor & TPS harness connector and chassis ground.
  Specification : Approx. 12V
5. Is the measured voltage within specification?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Go to 2"Check open in harness" as follows.
Check open in harness
1. IG "OFF"
2. Disconnect ETS motor & TPS connector and PCM connector.
3. Measure the resistance between terminal 2 of ETS motor & TPS harness connector and terminal 2 of PCM harness connector (C144-A).
4. Measure the resistance between terminal 3 of ETS motor & TPS harness connector and terminal 1 of PCM harness connector (C144-A).
  Specification : Approx. below 1Ω
5. Is the measured resistance within specification ?
  YES
  - Go to "COMPONENT INSPECTION " procedure.
  NO
  - Repair Open in motor harness and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
